I need an in-sump skimmer for my 180. I got a full calcium reactor setup last year that I'm not using that I can trade. I am mostly doing LPS, so don't foresee needing this...and I definitely need a good skimmer. I'd love a SRO-3000, but I'm open to ideas. Let me know what you've got. Pm is key (because I get email notifications of pm).
